Unfortunately you haven't posted any useful information. Please check if it happens for all files in different folders. Try to create a new folder directly in the "albums" directory without any special characters and check again if it also doesn't work there.

None of the albums have special characters and yes it happens to all files in different folders. I did create an album in "albums" it only the date JAN31ST

Is there really no tooltip? For further investigation, I'd need admin access to your gallery. If you agree, I'll send you my contact details via PM.

Sure i agree to this.

Now this happening and I don't know why

I had a look at your gallery when you send me the login data and got the same what you reported. However, I had no time to have a closer look at it as I had some trouble with my own testbed.

I just had a look again, and now it seems to work - see attached screenshot.
